Determination of Reference Mechanical Angular Speed for Wind Power Systems

This paper analyzes the behavior of wind power systems at significantly variable wind speeds in time. That’s the reason why we have to determine the angular reference speed, so as to achieve a maximum capture of wind energy over a longer period of time. This paper determines the behavior of the system wind turbine (WT) synchronous generator (SG), considering the speed/mechanical angular velocity n ref/ω ref as reference in the control system. The control structure is based on the instantaneous wind speed measurement using an original model for the wind turbine. As the WT & SG system is nonlinear, the regulator tuning is done through numerical simulation.
